These Vitamin C capsules by far exceeded my expectations. I was feeling quite sick for a while; persistent cough, sneezing, runny nose, and body ache. For the last two years I had Bronchitis. I was almost certain I was developing Bronchitis again. Once I started taking these vitamins, my immune system felt stronger. I started feeling better. I would only beware of sucking on these tablets. I tried to suck on them because they were huge and I ended up with burns on my tongue that took 1-2 full days to heal. Chew them in half and swallow them. These vitamins are strong and you feel the difference within a day (especially if you're feeling sick)
